Abstract The speciose insect order Lepidoptera moths and butterflies and their closest relatives, Trichoptera caddis fliesshare a female-heterogametic sex chromosome system. The silkworm shares the last step, dsx, of the hierarchical sex-determining pathway with Drosophila and other insects investigated, but probably not the intermediate steps between the primary signal and dsx.
